In Sandvik's production of steam generator pipes, products occasionally arise that do not meet the standard for Sandvik's requirements. This leads to possible risks in connection with manual cutting with an angle grinder and bundling of pipes that can lead to a collapse during transport. The purpose of the work is then to create a concept for a redesign of existing scrap shear from strip manufacturing, so that it can flatten and cut the steam generator pipes.

As much as is reasonable of the machine must be preserved. Based on analyzes, the lever, attachments for hydraulic cylinders and engine, outlets from the machine and scraps were redesigned. As larger materials were to be processed, more power was needed in both rolling and cutting. Then essential parts need to be redesigned larger to provide space for newly purchased details.

Increased power requirements, mainly for the redesigned lever, mean that more space is required for purchase components and stronger materials. The frame needs to be completely redesigned. Some purchase components such as bearing housings and the entire construction for the shears can be reused, but it is recommended to design a new machine for the larger forces and use larger roll diameters.

Further future work that is recommended is to contact the company Hiak for production of sound covers as the machine's sound level is above the approved level, and to perform new assessments of the machine due to CE requirements for redesign and new production of machines, and a cost estimate for the redesign any cost.
